For those who don't have a wealth of travel experience and, more importantly, don't know any foreign languages, it makes sense to book tours in Seoul, which can cost from KRW 54,000 per person and KRW 110,000 per group.
If you want to get to know the capital in a short amount of time, take a Seoul sightseeing tour, which includes visits to the main sights and central districts. The best option is to take a bus tour of Seoul on a regular tourist bus. If you come as a family, Russian tours in Seoul with visits to the oceanarium and local parks are optimal.
